Portable drinking water in a disposable plastic water bottle is an on the go convenient way to quench thirst. During a segment of Oprah's Going Green 101, first aired on Earth Day 2007, Treehugger's Simran Sethi explained that plastic bottle manufacturers use five liters of water to make the plastic bottle that holds the one liter of bottled water purchased at the store. Not very green.

But wait. Bottled water has become an integrated part of our daily routine. If it's not green to purchase water in plastic bottles made this way, is there an alternative to keeping us hydrated and easy on the planet's most valuable resource? Yes. Reusable water bottles. Sethi offers these three green alternatives to the bottled water from your local grocer.

Nalgene water bottles, SIGG water bottles and the New Wave Enviro Corn-resin bottle with a filter. The latter is a biodegradable bottle made from corn, can be safely refilled up to 90 times before being commercially composted, and the carbon based Better Water Filter removes chlorine and organic contaminants lurking in regular municipal tap water.
